+Build 82 fixes the migration edge discovered by the first Build 81 production
+cycle: an explicitly unassigned Build 80 observation remains visible in the

 Build 77 separates the directional learner's evidence lineage from the global
 strategy release. Code-history verification found the same trend/reversal
 generator and 24-hour/72-hour grading policy in Strategy 51 through Strategy
